How do I make a target behave like

resource

in the sense that if Python code depends on it, the target’s source file is also bundled when the Python code is packaged as a PEX? Adding a

BuiltPackage

rule for the target is the closest thing to (what seems like) a solution I can find by just scrolling through existing backends, but unsure if that’s the right path. Those existing backends seem to all have a need to do something with the file before packaging it, which I don’t.

From a plugin, you'd want to make a codegen rule that generates a

ResourceSourceField

Codegen rule it is. Thanks!
